Strap for Benu Tourbillon White Gold / Silver

The lug width of the Moritz Grossmann Benu MG-000004 is 18 mm. This measurement represents the distance between the two suspension points of the case. To verify this, use a digital calliper and measure the distance between the lugs: it must be exactly 18 mm. All compatible straps must present this precise width to ensure ergonomic and aesthetically correct fit on the 44.50 mm case.

For the Benu MG-000004, we recommend dark brown alligator leather with natural grain or shell cordovan. Alligator maintains formal elegance that enhances the white gold case, whilst cordovan develops an intense patina that evolves over time. Both must be mounted on a brushed steel deployante to ensure secure closure. Your choice depends on personal style: prioritise daily practicality with aesthetic dignity.

To change the strap, position the watch with the case facing upwards. Use a thin and precise spring bar tool. Insert the flat tip into the lateral opening of the lug, gently push down the internal spring and remove the lug from suspension. Repeat the operation on the other lug. Install the new strap by reversing the procedure, ensuring that the lugs are fully inserted and locked. Avoid forcing: the mechanism must engage smoothly.

Yes. Any strap designed for 18 mm lugs is compatible with the Benu MG-000004. High-quality aftermarket straps, made from alligator, cordovan, calf leather or NATO fabrics, are perfectly mountable. The key is to verify the exact lug width and choose straps from specialised makers that respect quality standards. On milanostraps.it you will find a curated selection of 18 mm straps suitable for this model, with customisation options and deployante finishes.

A premium leather strap, such as alligator or cordovan, guarantees a lifespan of 3-5 years in daily use, extendable to 7-8 years with proper maintenance. Cordovan is particularly durable due to leather density; alligator requires more attention to moisture. Determining factors: frequency of use, exposure to water and perspiration, periodic conditioning with specific creams, rotation with other straps. A vegetable-tanned calf strap has a slightly shorter cycle (2-3 years), but develops a fascinating patina that characterises it. Cotton or perforated rubber NATO straps last 4-6 years before replacement is necessary.
